To all whom it may/. concem:

Be it known' that I, ANDREW B..LIP'SEY, of` West `Hohoken,"in the countyof Hudson and State of New Jersey, have invented certain Improvements`in Pulverizing-ll/Iachines, of

One improvement consistsin the combination of a series of chambers of'successivelylarger diameter, arranged one outside or be yond theperiphery of another, and series of tremely-compact, simple, andserviceable pulverizing-machine is produced.

Another improvement consists inthe combination, with a chamber providedwith.' a `series of revolving beaters,of a chamber of larger diameter,communicating with the former, and provided with a series of beaters,revolving in the same length of time as thoseV in the at a greaterspeedq producing `a partial vact num and drawing from the smallerchamber the lighter particles of the material therein pulverized,whereby I produce a very simple and superior pulverizing-machine, whichmay be operated with a very Asmall amount of power.

Another improvement consists in the com-` bination, with a chamber`provided with a se ries of revolving beaters, of a chamber of' largerdiameter, communicating directly with the smaller chamber, and providedwith a series of beaters, supported on the same shaft as those of thesaid smaller chamber, and revolving in the same length of time asthelat-` ter, whereby I produce a simple and exceed- Another improvementconsists in the combination of two or more chambers, communicating onewith another, and provided each with a series of beaters for revolvingtherein, andialsoprovided with lips overlapping the beaters of eachchamber, which communicates with another, whereby material to'bepulverized therein is prevented from passing out of one chamber intoanother, except at the proper place.

Another improvement consists in the cominlet for supplying material tobe pulverized,

and air, or its equivalent, thereto, of means for regulating or shuttingoff the supply of" material, and air, or its equivalent, wherebyprovision is afforded for supplying them in the proper relativeproportions, in such manner that theY air orv its equivalent will 4notinterfere with the said material in its passage through the machine, andfor entirely Yshutting olf the bination, with a beater extendinglongitndinally outward from the side ofa disk or spider of a renewableshoe, fitting or lapping over over the face, inner` edge, and outer endof such beater, a dowel or projection on the outer end of said beaterfitting a cavity in the contiguous portion of the shoe, and a rivet orbolt atthe inner end Aof the shoe securingrit to the aforesaid disk orspider, whereby pro 'vision is afforded for properly securing the shoein place withoutperforating, and thereby weakening, the beatertransversely.

Other improvements consist in details of construction, to be hereinafterexplained.

In the accompanying drawing, Figure l `is a partly-sectional side viewof a pulverizingmachine embodying my improvements.` Fig. 2 is atransverse section thereof.

A designates a chamber, preferably of cylindrical form externally,'aswell as internally, and VB designates a series of beaters capable ofbeing revolved therein. C designates an inlet for the material to bepulverized, and air, or its equivalent. It is shown as communicatingwith the chamber A at the side, vand is provided with a throttle,D,'which may be shifted to regulate the passage of the material to bepulverized, and air, or its equivalent,into the chamber A- The throttle,though represented as consisting of a simple cock, ,may consist of ,aslide, or any other device which may be made to effect the throttling,narrowing, or closing 'of the inlet.

Above vthe throttle the inlet is preferably provided with a hopper -toreceive the material to be/pulverized from a feeding-chute, E, and thespacebetween the'klatter andthe hopper affords provision for theentrance of air or its equivalent.

Great Aadvantages result `from admitting and regulating the admission ofthe material to be pulverid and air or its equivalent by the same meansinto a` pulverizingmachine. In this way one continuous p as- ,sage ofboth ythrough the machine may be effected, the disturbance of thematerial to be 1 the machine.

The beaters B are preferably provided with renewable shoes, hereafteritobe described, and are shown as supported by a spider or disk,

vS, which is xed to a suitably-supported rotary shaft, F, and may serveto form one side of the said chamber A. A1 designates a chamber, whichis of larger' diameter than the chamber A, communicates therewith, andpreferably is also cylindrical externally as well asinternally. B1designates a series of beaters supported -by a spider or disk, S', fixedto a rotary shaft, F, and capable ofrevolvingwithin the chamber A1. A2designates a chamber, which is of larger diameter than the chamber A1,communicates therewith, and is ,preferably also `cylindrical externallyas well as internally.l yB2 designates a series of beaters capable ofbeing revolved within the chamber A2.

The chambers A and A1 communicate, respectively, with the chambers A1and A2, and are shown as communicating therewith at the sides.

`on the same shaft.

outer parts of the beaters B and B1 of the chambers A and'A, so as toprevent the material pulverized in these chambers from passing into thechambers with. which they, respectively, communicate.

In order to provide for placing the beaters in their position for work,the inwardly-.projecting parts of thev lips Gr G are notched, as shownin Fig. 1, to permit them to pass beyond them.

The exit-opening H H1 of the chambers A and A1 are :shown as ybeing madeby leaving off lportions of the lips G and G', and for the sake ofclearness are blackened throughout their extent. They may, however, bemade in any other suitable manner. Provision is afforded for the exit ofthe pulverized material and air or its equivalent from the chambervA2 bytwo openings, H2, in its periphery, (shown one in Fig. l and both inFig. 2,) and also blackened throughout their extent. These exitopeningspreferably communicate with an outlet, I, supported yon the chamber A2or otherwise, sol that by means of' a set-screw, a, clamping it to itssupport-tackle consisting of cords and pulleys or other means-it may beadjusted at different angles without severing its communication vwithsaid exit-openings H2, and may be securedin position.

The outlet I, in order to afford provision for automatically separatingline and light from coarse and heavy particles of the pulverizedmaterial, is provided, preferably at the bottom, with an opening oropenings, o, which may with advantage be rearwardly inclined. Whensupported as represented, this outlet I is ,preferably provided with anadjustable top portion, which may be shifted, so that none of thepulverized material can escape under any circumstances. For instance,when the outlet is elevated the main top portion will ymove inward underthe adjustable top portion,

and when the said outlet is depressed the adjustable top portion will bemoved inward.

As represented in Figs. l and 2, the several chambers A A1 A2 are madein one piece, and the chamber A1 is outside the chamber A, and thechamber A2 outside the chamber A1; but in Fig. 3 the chamber A1 isarranged at the side of the chamber A, and the chamber A2 is arranged atthe side of the chamber A1, but in both examples the spiders or disksfor supporting the several series of beaters are shown as made in onepiece, and are rotated They may be made in either of these ways withadvantage, especially the former, as `thus the greatest compactness maybe obtained; but they may also be any suitable manner.

J designates a cover, which is arranged outside the spiders or diskssupporting the beat- I ers and covering them.

An important advantage of making each fseAol e f l er taylor thechambers extenany cylindrical is, that it may be moved from `place toplace The operation is as followszfMate/rial to be 1 pulverized andtheproper relative proportion y tion of such material. The beaters B1,revolving in the chamber A1 in the same length of time as the beaters Bin thechamber A, but

" moving at a greater speed, owing to the increased radii of theirrevolution, produce a partial vacuum at the exit-opening H of thechamber A, draw from the latter the lighterparticles ofthe pulverizedmaterial, and cause them to be pulverized still more.` rlhe beaters B1,revolving in the chamber A2 in the same length of time as the beaters Band B1 in the chambers A and A1, but moving at a greater speed,` owingto the increased radii of their revolutioi'produce a partial vacuum atthe exit-opening H1 of the chamber A1, draw from the latterthe lighterparticles of the pulverized material, cause them to be pulverized stillmore, and discharge them into the outlet I. This outlet may be inclinedupward,

, so that the force of the escaping air, or its equivalent, will besufficient to carry only the lighter particlesout through the endthereof, and the heavier particles will then be discharged out of theopenings o.

Any number of the said chambers may be used. For pulverizing somematerials more may be needed than for pulverizing others.

Itwill have been seen that `by these improvements` I provide for makinga very simple and exceedingly compact pulverizing-machine, which can beoperated with but a small amount of power,and can be easily managed andmoved from place to place.

When pulverizing moist material it may be advantageous to arrange theexit-opening of the chamber from which the material is to be deliverednear the bottom, and to an apartment below.

It is` obvious that additional series of beaters might be arranged onthe other sides of the spiders or disks S, S1, and S2, to work inanother set of chambers without entailing the expense of additionalshafting and other parts. It is also obvious that a number of sets ofbeaters and chambers may be arranged side by side on the same shaft,with economy.

I will now describe the removable shoes or faces K for the beaters, andthe meansfor securing them in place, premising that they are not theonly `Kind that maybe used.

These shoes K are preferably made of steel, and cover the faces and theinner sides and the ends of the beaters which are farthest from thespiders or disks S` S1 S2.` By overlapping at the inner sides ofthebeaters they are secured againstoutward displacement by centrifugalforce. Theyare secured against Ymovement outward by pins or dowels c,projecting into'them from the beaters. Bivetsf, .impingingon the outersides of the disks or spiders, `secure them against displacementllengthwise. Thismanner of securing them is very desirable because ofitsV simplicity and effectiveness. l
